I cannot the quasar play app working on my phone. :(

To start with I’m a total n00b and I have spent a fair few hours of troubleshooting and googling, so I thought it’s time to ask the experts.

I’ve been stuck with getting Cordova barcode to work on my app.
So I thought, I will checkout the Quasar Play app and build it and see how this work and then copy it to my app. To my surprise though, the Quasar App (current master & dev) don’t work for me! That is when you “Play Url” -> Bottom right FAB -> “Phone Icon”.

The steps I took were to checkout the project run yarn in the root folder, then yarn in the /cordova folder.
Then back to the project root to run quasar dev --play.
